This necessitates placing firstly on the consecutivepoints on the dial the consecutive loops in one course formed at onelongitudinal edge of the binding, then running on the same points theconsecutive loops in a course at the marginal portion of the knittedfabric, finally placing on the points the consecutive loops in thecourse formed at the other longitudinal edge of the binding.

These steps cannot be carried out at great speed and require aparticular skilfulness of the operator. The method is therefore slow andexpensive, moreover skilled operators are not readily available.

Any inaccuracy in running the loops onto the points results in startingpoints for ladders in the finished article. The binding strip should beprovided with selvedges and is therefore made of ribbed knit.

The invention obviates the above drawbacks by providing a method ofattaching binding or trimming strips to parts of knitted articles ofwear on a linking machine, by which the strip and article to which thestrip has to be attached can be placed on the points with accuracy usingin the less expensive so-called casual manner which is already known andemployed in sewing knitted articles on linking machines such as forclosing the toes of stockings.

A further object of the invention is to provide a method of the typereferred to above which can be mechanized by the use of special guidesadapted to facilitate casual running of the loops in the strip andarticle onto the points on the dial of the linking machine.

A still further object of the invention is to provide guides adapted tofacilitate and expedite work.

With the above objects in view the invention provides a method ofattaching binding strips and knitted articles on a linking machine,which distinguishes by comprising the following steps:

a. forming a knitted binding strip provided with auxiliary longitudinaltabs extending from the opposite edges of the actual strip to beattached to the knitted article;

b. running the knitted article and strip onto the points on the rotarydial of a linking machine in such manner that the strip takes a channelshape, one at least of its tabs being juxtaposed to the inner channelface, in such manner that the marginal portion of said knitted articleextends a certain length within the channel;

c. forming on said linking machine a chain-stitch seam joining theopposite edge portions of the strip to the knitted article.

According to a preferred embodiment of the invention the auxiliary tabson the strip are formed at least at their portions adjacent the knit ofthe actual strip of a smaller thickness than the knit of the actualstrip.

According to a further feature of the invention in order to makepossible the use of guides for placing the strip on the points on therotary dial of the linking machine the tabs on the strip are formed witha first section adjacent the knit of the actual strip of a smallerthickness than the knit of the actual strip, and with a further marginalsection of increased thickness with respect to the former.

FIG. 21 is an elevation of a detail of the construction shown in FIGS.18 to 20.

Corresponding parts are denoted by the same reference numeralsthroughout the figures.

By the embodiment of the method shown in FIGS. 1 to 4 the actual bindingstrip 1 is formed with longitudinal tabs 2,3 extending beyond its edges4,5, respectively. The tabs 2,3 are less thick than the knit of theactual strip 1, said tabs being preferably knitted from a yarn otherthan the strip 1, such as elasticized yarn. They can be made of ribbedknit if they have to be provided with a selvedge. The knit of the actualstrip is preferably of the ribbed type.

The knits to be joined are impaled on the points on the rotary dial of alinking machine by firstly bending over the tab 2 on the actual strip 1to juxtapose the face 2a of said tab to the face 1a of the strip whichis coplanar with the former. Thereafter the loops belonging to thecourse forming the edge 4 of the strip 1, or possibly the loops in anearby course, and the loops in one course in the tab 2 are impaled oneach of the points 6 on the rotary dial of the linking which is notshown in FIGS. 1 to 4, 5,9 and 12. The loops in one of the courses in aknitted article 7, spaced from the edge 7a are impaled on the points 6in order to reach the arrangement of the parts shown in FIG. 3.

The next step consists in bending the tab 3 over on the actual strip 1to juxtapose the face 3a of the tab 3 on the face 1a of the strip. Thestrip is then folded to channel shape, and the loops in the coursedefining the edge of the strip or in an adjacent course are run onto thepoints 6, thereby completing assembly of the parts on the points 6 onthe dial, which by revolving with the latter move the knits to be joinedto the operau'ng region of the tools U of the linking machine adapted toform a chain-stitch seam 8 (FIGS. 4 and 7).

As will be understood from the drawings and foregoing description theedge portion 722 of the knitted article to be connected to the stripextends a certain length within the channel formed by bending the stripS to U- shape and the opposite faces of said edge portion are adjacentto the channel as shown in FIG. 4.

By the above method notwithstanding casual impaling no runs can beinduced either in the article 7 or the strip 1 which can therefore bemade as a tubular knit. The presence of the knitted article 7, marginalportion 7b and tabs 2 and 3 on the strip 1 safely prevent runs.

According to a modified embodiment, the actual binding strip ispreliminarily formed with two longitudinal tabs differing in form. FIG.5 shows a strip of this type which is provided at its edge 4 with afirst tab 2 similar to the one shown in FIG. 1 and at its opposite edge5 with a further tab including a first section 9 knitted of a thicknesssubstantially less than the knit of the actual strip, and an outersection 10 of increased thickness equalling the thickness of the strip.The section 9 is knitted from a yarn other than the strip, preferably anelasticized yarn, whereas the section 10 can be knit from the same yamas the strip, and the section 9 can be knit from a separating thread forthe purpose explained hereafter.

Assembly. of the strip 1 and knitted article to which it should bejoined, is effected in the manner described with reference to FIGS. 2 to4.

FIG. 6 shows the resulting article still on the points on the dial. TheFigure shows that the provision of the tab 9, l0 facilitates runningonto the points 6 of the loops in the actual strip, near the edge 5.This tab can be removed after completion of the seam. To this end itwill be sufficient to pull the said separating section 9. In the lattercase the portion of the strip ll near the edge 5 shall convenientlyinclude a few ribbed courses.

The method of the invention can be easily mechanized in part. For thispurpose the circular bedplate 1 1 (FIG. 7) of the linking machine,situated within the rotary dial 12 carrying the points 6 has securedthereto three guides generally denoted by A, B and C.

The method can be carried out by employing the guide A only. The stripis then arranged to take the shape shown in FIG. 8, by which the edgeportion 4 of the strip to be first impaled on the points is formed witha first tab including a first section 15 preferably knitted fromelasticized yarn, differing from the tab 2 on the previously describedstrips in that it is centered with respect to the thickness of thestrip, and is followed by a section 16 of increased thickness alignedwith the strip 1.

The tab extending from the edge 5 of the strip shown in FIG. 8 issimilar to the tab 3 on the strip shown in FEGS. 1 to 4.

The guide A comprises an elongated body portion 17 formed with anupwardly open groove 18 closed on the side of the body portion turnedtowards the rotary dial carrying the points 6 by a wall 19 the outervertical face 19a of which acts as a bearing surface for the portion ofthe face la of the strip 1 near its edge 4. The straight groove 18 isalmost completely closed at the top by an elongated plate 20, thetapered edge 20a of which is turned towards the rotary dial, definestogether with the upper portion of the other face 19b of the likewisevertical wall 19 a narrow slit 21, FIG. 7, extending parallel to thevertical wall 19. The guide further comprises an elongated plate 22(FIG. 7) arranged above the rotary dial 12 slightly spaced from theplane of movement of the points 6. The elongated plate 22 is connectedto the plate 20 and body portion 17 of the guide by means of straps 23and is connected to the stationary circular bedplate 11, FIG. 7, bymeans of bracket M. The plate 22 is formed with a tapered edge 2211turned towards the outside of the rotary dial 12, the edge 22b of whichdefines together with the top edge of the wall 19 a narrow slit 24extending parallel to the slit 21.

The guide A is so arranged with respect to the rotary dial 12 that theparallel slits 21, 24 are situated in vertical planes intersecting theannular path over which the points 6 move during rotation of the dial 12in the direction of the arrow 25.

In order to facilitate impaling on the points 6 of the portion of thestrip 1 near the edge 4, the face 1a of the latter is juxtaposed to theface 19a of the wall 19, FIG. 9, at the end of the latter remote fromthe dial 12. At the same time the thinner portion 15 of the first tabextending from the edge 4 is bent over around the edge 19c of the wall19, the thicker section 16 of the said tab being fitted into the groove18. As a result, displacement of the strip in the direction of the arrow26, FIG. 7, will enable the edge 4 of the strip 1 to adhere to thebottom face 22a of the plate 22 near the edge 22b, thereby aligning theloops in the course forming the edge 4 and arranging them at the levelof the points 6. The edge 4 of the strip is maintained at this level andthe strip 1 is kept adjacent the wall 19 by the adherence of the thickertab section 16 extending beyond the strip edge 4 and lower face 20b ofthe plate 20 and the step in the top portion of the face 19a of the wall19. The difference in height of the faces 20b and 22c of the plate 22 issuch as to stretch the section 15 on the tab extending beyond the edge 4of the strip.

In order to automatically run onto the points 6 the loops in the coursenear the edge 4 of the strip, it will be sufficient to move the stripseated in the guide as described above in the direction of the arrow 26,FIG. 7, to the position at which the loops start being caught by thepoints 6 travelling over a slightly lowered portion 190 of the edge 190.As impaling of the loops starts the strip is automatically carried intothe guide by effect of the rotation of the points 6 in the direction ofthe arrow 25. Impaling is facilitated by the provision of a loose roller27 carried by the body portion l7, formed with a circumferential groove28 into which the point ends fit. The further necessary steps forcompleting irnpaling on the points 6 of the loops in the elements to bejoined are effected in the manner described above with reference toFIGS. 3 and 4.

In order to carry out the modified method by which also the edge 5 ofthe binding strip is impaled on the points 6 by the use of a guide, thestrip is knitted as shown in FIG. 11. In this case the edge 5 of thestrip is formed with a tab similar to the tab 3, 110 of the strip shownin FIG. 5. The guide B is then employed for impaling the loops in thecourse in the strip 1 defining the edge 5 or in a nearby course. Theguide B comprises two plates 29, 30, arranged slightly above the annularpath of the points and defining a preferably straight slot 31. Theplates 29,30 are mounted in a frame 32 carried by a slide 33 providedwith a plurality of castorwheel pairs 34, 35 in crossed relationship asshown in FIG. 14, running over inclined tracks 36,37 provided in astationary circumferential flange 38 beneath the rotary dial 12. Theslot.31 starts externally of the circular path of the free ends of thepoints 6, extends parallel to the annular path of the latter and endsinternally of the circular path 39 followed by the free ends of points6. The frame 32 has journalled thereon a roller 40 formed with acircumferential groove so arranged that the points 6 travel over saidgroove 40a. In order to use the guide B for impaling on the points 6 theedge portion of the strip 1 near the edge 5, a few loops near the edge 5of the strip 1, situated at the end of the latter remote from the guideA are first run onto the points 6 at a region spaced from the guide A byan extent exceeding the strip length, of course after having impaled bymeans of the guide A the other marginal portion of said strip 1 and themarginal portion 7b of the knitted article 7. The guide B is then movedin the direction of the arrow 41, that is, towards the guide A, carebeing taken to cause the thinner section formed by the separating threadof the second tab on the binding strip through the slot 31. By movingthe guide B in the direction of the arrow 41, the second tab on thestrip is automatically impaled on the points with the assistance of theroller 40. A small cutter 42 shown in FIG. 16, which may be arrangedacross the end portion of the slot automatically cuts the separatingthread 9 and severs the thickened portion E0 on the second tab.

By means of the third guide C impaling on the points 6 also of themarginal portion 7b of the knitted fabric to which the strip 1 should bejoined is caused to take place in a semi-automatic manner. The guide Cshown in FIG. 17 comprises a Ushaped channel 433 which is open upwardlyand is preferably straight. The channel comprises two parallel portions,45 and a bottom portion 46 fast with the wall 44. The channel isdirected towards the inside of the circular path 39 of the free ends ofthe points 6 and diverges from the circular path in the direction of theguide A. The wall 44 is formed at its end portion near the points 6 witha longitudinal notch which the points travel, and at its opposite endwith an extension b bent over almost tangentially to the circle 39. Thewall 45 is nearly tangential to the circle 39 at the region in front ofthe notch 44a so that the points travel across the channel 43. Thebottom wall 46 is fully beneath the path of the points and slopesupwardly towards the channel end remote from the guide A. A roller 47 isloosely mounted near the channel end turned towards the points and isformed with a circumferential groove 47a through which the points 6travel. The roller 47 operates similarly to the rollers 27 and describedabove. The wall 44 is secured to a web carried by a slide 439displaceably mounted over the tracks 36 and 37 in the stationary flange38 by means of roller pairs, one roller pair 34 only being shown in FIG.17, the roller pairs being similar to the rollers 34 and 35 on the slide33. The wall 45 may be tilted in the direction of the arrow 50 againstthe action of the spring 51. The roller 47' may be tilted with itsrespective support about the pivot 53 in the same direction with respectto the slide 49, after having lifted the hook 54 holding together thesupports 52 and 48. During use of the guide C, effected after use of theguide A, the guide C is firstly removed from the guide A by an extentlonger than the strip. The roller 47 and wall 45 of the channel are thenbent over in the direction of the arrow 50 and a few loops in themarginal portion 7b of the knitted article placed on the bedplate 11 areimpaled on the points 6 having mounted thereon the strip end remote fromthe guide A. The roller 47 and wall 45 are then lifted and the slide ismoved in the direction of the arrow 55, whereby the portion 7b of theknitted article 7 is run onto the points.

The modified embodiment of the guide A shown in FIGS. 18 to 2b difi'ersfrom its embodiment in FIGS. 7 and 9 firstly in that the wall 19 isformed at the top of its face 19a with a step 19d adapted to abut theportion of the strip edge 4 situated on the side of the section 15turned towards the face la of the strip, FIG. 8.

The face 19b of the wall is in turn formed with a longitudinal throughrecess 19e adapted to receive one half of the thickened portion 10 onthe second tab. The face 19a of the wall 19 is moreover formed with agroove 19f, FIG. 19, which lets the points through.

-Moreover, the plate 24) starts a certain extent off the edge 19g of thewall 19 to accommodate a disc-shaped brush 56 rotating in the directionof the arrow 57 by an electric motor or a drive derived from a rotarymember of the linking machine (not shown). The brush is convenientlysupported by any of the stationary components l9 and 22 and istangential to the face 19b of the wall 19 in order to stretch thesection 15 of the first tab on the strip and insert the section 16 intothe groove and beneath the edge 20a of the plate 20, respectively. Inorder to separate the bulged portion 16 from the section 15 of the firsttab already on impaling of the edge dof the strip on the points, acutter disc 58 is rotatably mounted in the plate 20 and rotated such asby an electric motor 59 beneath the roller 27 which can then besupported by the plate 22. The disc 58 is situated above the plate 20and is coaxial with the roller 27 and of a diameter such that itscircumference finds its way over the top edge 60 of an extension 61 onthe wall i9 situated beneath the points 6. In the abovedescribedstructure the guide A may end at the level of the rollers 27 and istherefore shorter than the guide shown in FIGS. 7 and 9.

The finished article obtained after completion of the seam is shown inFIG. 13, in which a portion of the section of the first tab on the stripand its respective section 16, as well as the second tab 9,10 are shownby dotted lines to denote that they have been removed during impaling bymeans of the guides A,C, before effecting'the seam.

In the casein which the points 6 are inclined with respect to thehorizontal, the wall 19 should be perpendicular to the tangent plane tothe frusto-conical zone traversed by the points. 1
